List lookup control height change

could you post a screenshot to see what problem do you exactly experience?

how do render the control (display format)?

height resp. number of rows of multiselect lookup control is fixed by design (7 rows if I recall correctly)

it's only changeable with javascript.

size of buttons is not configurable either, but I'd say they might be enlarged with a javascript or CSS as well.

with CSS you can achieve it eg. as follows

- add a 'CSS class'  to lookup control (eg. MSLL)

- define style for the class in form settings >> custom CSS, eg.

.MSLL button{
   width: 200px !important;
   height: 100px !important;
}‍‍‍‍

don't you apply any other CSS on the element that my overrule this settings? or don't you manipulate control with a javascript?

for me it works...

try rather on published form, preview need not always work reliably

Now, is there anyway to call the add or remove button through javascript? I need to do some validation when the add button is clicked.

so do you want to trigger or handle button click event?

try code like this

NWF.FormFiller.Events.RegisterAfterReady(function () {
    NWF$('#'+MSLL).parent().find('button.addSelectedItems').click(function(){
        console.log('Add pressed');
    });
    NWF$('#'+MSLL).parent().find('button.removeSelectedItems').click(function(){
        console.log('Remove pressed');
    });
})
