    Im trying to expand/collapse wjFlexGridDetail on row click but i cannot find a way to make it work, also i dont want the row header i want to make looks like normal color, something like this:

    the issue is that the ExpandSingle doesnt work because im handling the expand/collapse with a gridClickHandler event:



    public gridClickHandler(e: any, grid: any) {
    if (!this.flexGridDetail) return;
    const ht = grid.hitTest(e);
    const isButton = ['wj-cell-maker', 'fa'].some( (className: string) =>;
    if (!isButton) {
    if (this.flexGridDetail.isDetailVisible(ht.row) && this.flexGridDetail.isDetailAvailable(ht.row)) {
    this.expandedRow = null;
    } else {
    this.expandedRow = ht.row;

    the issue with the code above is that the row.index increase when the rowDetail is displayed, so the row doesnt match as expected.

    so i want to make it that only one row can be visible at a time and make handle the toggle on row click, also i want to color the entire row when i hover or select, so if i add the rowHeader it doesnt color, i dont want this:

    I want to expand/collapse the nested grid when i click on the row, also i want to show a custom icon and i want that the entire row change color on hover and selection.

    so im facing 3 issues:

    1.- the RowHeaders doesn't change color on Selection / Hover, example:

    Is there a way to change the Color of the RowHeader?

    2.- I want to expand or collapse the Row on Selection change, so the expected behaviour is to click in any place in the Row and expand or collapse the Details i already try with the gridClickHandler but when i try to use that i cannot use the "ExpandSingle" and i can open more than one RowDetails at the same time.

    3.- I want to focus to the current Row that is showing the details, scroll down or up to make the Selected Row to looks like the it was a Header / First Item of the grid.

    btw, the custom icon help me to change the +/- icon and use caret, thanks for that one
