I have a list lookup field with approx. 300 entries (single line of text).
In the new items form it looks like two boxes and you can add items from the left box into the right one (you probably all know it).
My problem is that the box is so small (the width) that most you can just read the first two words of all the items. This makes it really inconvenient.
I tried to write some code to have a search-function, but I am not that good in programming so I couldn't find a solution that worked for me.
Do you have ideas?
For example change the SharePoint Designer 2013 code so the box isn't that small..?
