Hi,
I had upgraded jmix to version ‘1.5.0’ as per documents MultiSelectComboBox → JmixMultiSelectComboBox (multiSelectComboBox in XML) is avaible but the same is not available in xml.
Hi,
MultiSelectComboBox isn’t available for Classic UI, only for Flow UI. Since I see caption on your screenshot, you’re either using Classic UI or incorrect xmlns.
