Hi,
First of all, thanks to knime team to providing an interesting webui component. Recently I’ve started to develop a node using it but in some situation I want to be more flexible to customize dialog components. For example in the below picture which shows ColumnRenamer node, How can I delete the add Column button or dustbin icon in front of horizontal layout?
As a try, I delete addButtonText of option from that element in uischema.json but didn’t worked!

knime-version: 5.1.0
