    I use Flexgrid, and have a dropdown CellTemplate inside flexgrid.

    if i frozen column after this dropdown cell, the dropdown will not work
    E.g. FrozenColumn(5), Dropdown column index 3.

    if i frozen column before this dropdown cell, the dropdown will work fine.

    even i try in ComponentOne MVC Explorer demo application, it's same issue.

    please advise how to make dropdown work when got frozen column after dropdown.

    Thanks Manish, any workaround about this function before the Team fix this?

    We get response from the development team.
    The issue was because of z-index for frozenCells is set to 1 which covers the customEditor.

    Please find the attached sample which implements workaround for this issue by setting customEditor's container z-Index.

    We are sorry, we do not have any exact release date for next release. The next release should be in mid or end of July.

    Please try to invalidate the Wijmo Control on resize event for Jquery-UI resizable.

    Could you please share code snippet how you are adding Dropdown for frozen column. Is the Dropdown placed for cell or for edit cell?

    Hi Manish

    I just define a DIV with dropdown

    <div id="tplDropdown" class="dropdown">
    <button class="btn btn-secondary dropdown-toggle" type="button" id="dropdownMenuButton" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
    <div class="dropdown-menu" aria-labelledby="dropdownMenuButton">
    <a class="dropdown-item" href='javascript:;' onclick='Test0()'>Test</a>
    <a class="dropdown-item" href='javascript:;' onclick='Test1()'>Test</a>
    <a class="dropdown-item" href='javascript:;' onclick='Test2'>Test</a>

    then in FlexGrid ItemFormatter function to replace current cell innerHTML as below.
    cell.innerHTML = document.getElementById('tplDropdown').innerHTML

    Is the Dropdown working for non-frozen columns?
    If yes, please try to set CloneFrozenCells to false.

    Could you please share build version?

    Please also find the attached sample that is used to replicate the issue at our end but we are unable to see dropdown for Non-frozen cells because of dropDown gets hide behind cells.

    Please let us know if the behavior is same at your end.
