Filtering buttonSelcet in toolbar

Dear all,
is it possible to enable filtering within the item buttonSelect at toolbar.
the dhtmlxCombo allows filtering:

Is there something comparable for buttonSelect?

I added the button as follows:
aToolBar.addButtonSelect(‘sel_item’, 6, ‘’,‘’,null, null, true, true, 10,‘select’);

There is no netive approach, but you can try to use combo in toolbar - it can be filtered and used as select menu.
Attaching combo to toolbar:

<style> .dhx_toolbar_base_dhx_skyblue div.dhx_toolbar_text { margin-top: 3px !important } .dhx_toolbar_base_18_dhx_skyblue div.dhx_toolbar_text { margin-top: 3px !important } </style>

dhxToolbar.loadXML("dhxtoolbar.xml, function(){ dhxToolbar.addText('cb', 5, '<div id="combo" style="width:200px; height:30px;">'); dhxCombo = new dhtmlXCombo("combo", "cmb", 200); }"); … filtering/ - combo filtering
