in the Advanced form, whenever using the multiple ressources scenario (AllowMultipleValues = true), all the ressources are displayed in a single column (as shown in attached image).
This is OK if there is less than 3 or 4 possible ressources, but becomes pretty ugly whenever there is 10 or 15 potential ressources. Would it be possible to consider for a future release to add a parameter to display the ressources in several columns ?
Another possibility would be to display the ressources as a multiple selection combo or listbox (with checkboxes).
