Colorpicker appears under the layout

The colorpicker is showed under Dhtmlx layout and not on it so it is impossible to use.

This is the code:

dhtmlxEvent(window,“load”,function(){

var main_layout = new dhtmlXLayoutObject(document.body, ‘3W’);
main_layout.cells(“b”).attachObject(“ThreeJS”)

var a = main_layout.cells(‘a’);
//a.collapse();
a.setWidth(‘200’);
a.fixSize(1,0);

var b = main_layout.cells(‘b’);
b.setWidth(‘600’);
b.hideHeader();

var c = main_layout.cells(‘c’);
c.setWidth(‘350’);
c.hideHeader();
c.fixSize(1,0);

var toolbar_1 = main_layout.attachToolbar();
toolbar_1.setIconSize(32);
toolbar_1.setIconsPath(‘./codebase/imgs/32/’);

toolbar_1.loadStruct(‘./data/toolbar.xml’, function() {});
toolbar_1.setAlign(“right”);

var myColorPicker = new dhtmlXColorPicker({
parent : “colorPicker”,
color : “#0000ff”,
custom_colors : true
});
myColorPicker.setPosition(100,100);
myColorPicker.show();
});

If you need separated colorpicker over the layout, you just need to set z-index for it. I.e.:
