Support custom values in buttons in the toolbar

[jhchen]

Currently buttons in the toolbar can only toggle a value on/off. It should be support custom values. For example to implement a UI where each text alignment icon is a button.

The concept of grouping/exclusivity will also have to be introduced for this feature to be useful. For example, the text align left and text align right buttons cannot be simultaneously on.

Has this feature being implemented yet? I couldn't find anything about this on the docs.

[jhchen]

No this is still an open Issue.

Any progress on this?

I'd like to see this as well. Is this moving forward?

This has been added in the beta release by setting a data-value attribute on buttons.
