Combo hasn't displayed in html

I have an issue.



I wrote this page (example down), but when I want to select an option of a combo, it doesn’t display… please… any suggest?



I suppose the reason is the lot of div’s in page… ‘cause the coe works in an external html (formed only for grid display purpose only).



Thanks.



























        





























































I think the problem caused by z-Index conflict, the options list shown, but it shown below some other absolute positioned elements. You can increase z-Index of option popup in next way

Locate in dhtmlxgrid.css file next style definition.
    .dhx_combo_select{
and add to it
    z-index:999; // or some other big value
