Hi Manolo,
Thanks for contacting Syncfusion support.
Currently we don’t multicolumns support in our ListBox control. But we can achieve your scenario in the sample side itself. This can achieved by overriding the CSS of the ListBox <li> elements and then adjusting the height and width of the control accordingly.
<style> .e-ddl-popup div > ul li, .e-ddl-popup div > .e-listbox li { display: inline-table; width: 108px; } </style> |
We have also prepared a sample for your reference below:
If the above sample and details do not meet your requirement, please give us more information that will help us provide the solution.
Regards,
Arun P.
