Do you mean our default Ribbon UI that we create for TdxRichEditControl?
I think that the easiest way to create these galleries for your existing UI is the following:1. Right click on TdxRichEditControl and select "Generate Ribbon/Toolbar UI...".
2. In the appeared dialog unselect all the check boxes except for "Home - Styles" and "Table Design - Table Styles".
3. Click OK.
4. Our UI generator should create corresponding UI elements in your TdxRibbon control. All you need is to move them into appropriate locations.
Please test this approach and let me know if it meets your requirements.
