User interface editor

1. A method, performed by one or more computing devices, comprising:

defining a hierarchical structure for a user interface (UI) via a UI editor, comprising:

receiving a first user input from a first user to define one or more layers of the hierarchical structure;

adding one or more UI components at each layer; and

specifying one or more relationships among particular UI components; and

associating metadata with each UI component at each layer, the metadata comprising display information describing how the corresponding UI component is presented in the UI based on defining one or more display states for each UI component at each layer and one or more user selections that cause each of the display states to be displayed on the UI,

wherein at least one of UI components is associated with a single display state and at least one of the UI components is associated with a plurality of display states,

wherein the at least one UI component associated with a plurality of display states comprises at least a default display state associated with the display of the UI component when it is determined that the first user has not selected the UI component, and a selected display state associated with the display of the UI component when it is determined that the first user has selected the UI component, the selected display state being different from the default display state,

wherein the default display state is associated with a static media object,

wherein the selected display state has one or more characteristics selectable by the first user,

wherein the selected display state of the UI component represents a transformation of the default display state such that one or more UI components and one or more relationships among the UI components is modified according to the metadata associated to the UI components, and

wherein the selected display state is associated with a user-interactable media object.

2. The method of claim 1 , wherein when a first UI component associated with a plurality of display states is selected via the UI editor by the user, the UI editor automatically edits the first UI component on a first layer of the hierarchical structure such that an upper border or lower border of the first UI component extends beyond a second UI component associated with a second layer of the hierarchical structure underneath the first layer.

3. The method of claim 1 , wherein one or more multi-state UI components are predefined or defined by the UI editor to be associated with a pre-defined plurality of display states.

4. The method of claim 1 , wherein the one or more UI components further comprise one or more of a text block, image, video, audio, feed, executable, website, web page, digital book, photo album, post, or message.

5. The method of claim 1 , wherein the one or more UI components further comprise one or more media objects.

6. The method of claim 1 , further comprising, for the at least one UI component associated with the plurality of display states, defining, via a UI designer, one or more user controls for accessing each of the plurality of display states.

7. The method of claim 6 , further comprising: selecting, via the UI designer, the one or more user controls for accessing each of the plurality of display states based on at least one attribute of the UI component.

8. The method of claim 1 , wherein at least one UI component is associated with a third display state that is user-accessible only when a user interacts with the UI component using a pre-defined user interaction.

9. The method of claim 1 , wherein the static media object comprises one or more of:

an image;

a text block;

a single frame of the user-interactable media object; or

an object with a set of user controls associated with the default display state.

10. The method of claim 1 , wherein the user-interactable media object comprises one or more of:

an image;

a text block;

a video;

an audio file;

a game;

a digital book;

a photo album;

a feed;

a web site;

a web page;

a post;

a message; or

an object with a set of user controls associated with the selected display state that is different from the set of user controls associated with the default display state.

11. One or more computer-readable non-transitory storage media embodying software that is operable when executed to:

define a hierarchical structure for a user interface (UI) via a UI editor, comprising:

receiving a first user input from a first user to define one or more layers of the hierarchical structure;

adding one or more UI components at each layer; and

specifying one or more relationships among particular UI components; and

associate metadata with each UI component at each layer, the metadata comprising display information describing how the corresponding UI component is presented in the UI based on defining one or more display states for each UI component at each layer and one or more user selections that cause each of the display states to be displayed on the UI,

wherein at least one of UI components is associated with a single display state and at least one of the UI components is associated with a plurality of display states,

wherein the at least one UI component associated with a plurality of display states comprises at least a default display state associated with the display of the UI component when it is determined that the first user has not selected the UI component, and a selected display state associated with the display of the UI component when it is determined that the first user has selected the UI component, the selected display state being different from the default display state,

wherein the default display state is associated with a static media object,

wherein the selected display state has one or more characteristics selectable by the first user, and

wherein the selected display state of the UI component represents a transformation of the default display state such that one or more UI components and one or more relationships among the UI components is modified according to the metadata associated to the UI components, and

wherein the selected display state is associated with a user-interactable media object.

12. The media of claim 11 , wherein when a first UI component associated with a plurality of display states is selected via the UI editor by the user, the UI editor automatically edits the first UI component on a first layer of the hierarchical structure such that an upper border or lower border of the first UI component extends beyond a second UI component associated with a second layer of the hierarchical structure underneath the first layer.

13. The media of claim 11 , wherein one or more multi-state UI components are predefined or defined by the UI editor to be associated with a pre-defined plurality of display states.

14. The media of claim 11 , wherein the one or more UI components further comprise one or more of a text block, image, video, audio, feed, executable, website, web page, digital book, photo album, post, or message.

15. The media of claim 11 , wherein the one or more UI components further comprise one or more media objects.

16. The media of claim 11 , the media embodying software that is further operable when executed to, for the at least one UI component associated with the plurality of display states, define, via a UI designer, one or more user controls for accessing each of the plurality of display states.

17. The media of claim 16 , the media embodying software that is further operable when executed to select, via the UI designer, the one or more user controls for accessing each of the plurality of display states based on at least one attribute of the UI component.

18. The media of claim 11 , wherein at least one UI component is associated with a third display state that is user-accessible only when a user interacts with the UI component using a pre-defined user interaction.

19. A system comprising: one or more processors; and a memory coupled to the processors comprising instructions executable by the processors, the processors operable when executing the instructions to:

define a hierarchical structure for a user interface (UI) via a UI editor, comprising:

receiving a first user input from a first user to define one or more layers of the hierarchical structure;

adding one or more UI components at each layer; and

specifying one or more relationships among particular UI components; and

associate metadata with each UI component at each layer, the metadata comprising display information describing how the corresponding UI component is presented in the UI based on defining one or more display states for each UI component at each layer and one or more user selections that cause each of the display states to be displayed on the UI,

wherein at least one of UI components is associated with a single display state and at least one of the UI components is associated with a plurality of display states,

wherein the at least one UI component associated with a plurality of display states comprises at least a default display state associated with the display of the UI component when it is determined that the first user has not selected the UI component, and a selected display state associated with the display of the UI component when it is determined that the first user has selected the UI component, the selected display state being different from the default display state,

wherein the default display state is associated with a static media object,

wherein the selected display state has one or more characteristics selectable by the first user, and

wherein the selected display state of the UI component represents a transformation of the default display state such that one or more UI components and one or more relationships among the UI components is modified according to the metadata associated to the UI components, and

wherein the selected display state is associated with a user-interactable media object.
