I just discovered that in version 4.6 I cannot use the mouse to activate the dropdown. I click inside of the combobox but I have to use my arrow keys to activate the dropdown and select. My combobox is inside of a tab control. I went back to version 4.1.2 and it worked fine. I’m testing with IE11.
I had the same problem. I solved it adding this :
combo_init.attachEvent( ‘onFocus’, function(){
combo_init.load(‘combo.php?mask=’+combo_init.getComboText());
combo_init.openSelect();
} );
Sorry for dragging old thread.
I’m facing similar issue with latest version. For demo one can also use dhtmlx combo online sample.
