Hi guys,
I make a form extension, and add a new TabPage for my new fields. In regards it is the form System Parameters, I should inform it is using Pattern : Table Of Content.
In my new TabPage, as usual there are Group : Body that I need to put a pattern as well. In this case I'm using Custom for the pattern ->

There are several FormStringControl under the group. And my issue is, how to make the control's length (which is a text box) to be in full length (according to its field length). Or at least I can make it lengthen.
Because currently this is what I got -->

In the UI, the content is displayed with part of it only and I need to go in each of the field to see what is the rest of my text content. There is also wide empty space on the right which not really intuitive for user to see.
But the important is I want to make the text box control wider.
Thanks,
