can we add select all button in twincol select component , curretnly component contains only two button right arrow and left arrow ,
but i want another two buttons like select all (see attched image) , when i click right all arrow it should select all va;lues from right and place it on left like vice versa .
You would need to create your own component or extension in order to add that functionality. I’ve created an add-on called
FilterableTwinColSelect which has the select all buttons. It also allows you to filter the content. Downside is, that it is not a drop-in replacement for the TwinColSelect.
Thanks for your support . But to match my requiremnet i have modified some parts in your add-on , Like - allowing only one filter , alignment and some filter chnages etc …
Can you please let me know your used source control system (ex- github) so that i can check in the code.
