Set menu open from the left side

This can be accomplished by applying custom styling and changes on the fluid-ui-block.html.twig file. I'm closing this for now

Sorry if I moved this to "Won't" fix to Active, it's been a while (years), but not that we widget can be enabled as a custom block, the widget can be placed anywhere, even in the sidebar, and with combination of some css tricks, this can actually work. Let me have a try and I'll let you know how it goes.

Sorry for reaching out to you a bit late @hillel33 !!!!!

Actually, It works !!!

What you need to do is to install the module as usual, then go to /admin/config/fluidui/adminsettings and check "Enable the FluidUI widget as a Block", then place the block in the sidebar of your theme (I'm using olivero in the example):

Then make sure to apply these styles in the ul inside the widget:

display: flex;
flex-direction: column;

Make sure to add the enough width to the sidebar in order for the widget to spread out with no problem

I'll leave this issue as "Needs Review" for now, just in case someone @hillel33 is still there, or someone will find this information useful, then I mark it as "Fixed".
