Conditional Style Manager properties

[adam3278]

Hello,
I want to move my styles section into new level. There is a need for select field with predefined colors (or something else) but with ability to choose option „custom”. Then the another property appears and it’s standard gjs property. This modification simplifies a lot making projects for newbies and people without design talent (as me). I also need to show and hide properties based on chosen css display mode (block, flex, etc.), but it can be obtained by adding and removing properties via js on event.
