Size of Multiselect list is not getting adjusted based on the source list size in PEGA 7.3
In Pega 7.3 the multi select list control is not dynamically adjusting its size as it used to do in the previous version. We could see the size specified in the parameter is getting passed to the control. Please see attached doc for screenshots.
Is this issue browser specific? Can you take the HTML code pertaining to the multiselect and display it in a standalone HTML outside of Pega, do you still see the problem?
MultiSelectList being a non-autogenerated control, I am not sure how much product support is available for this in 7.3. Have you taken a look at the 'Build a List' feature in UI gallery, would that help you in your requirements at all.
