How to remove the expand/collapse button from the jqGrid header?

 Yes, it is possible to remove the expand/collapse button from the jqGrid header.

To do this, you can use the hiddengrid: true option in your jqGrid configuration. This option hides the entire grid header, including the expand/collapse button. Here's an example:

javascript
$("#grid").jqGrid({
    // other jqGrid options
    hiddengrid: true,
});

Alternatively, if you want to keep the grid header visible but remove only the expand/collapse button, you can use CSS to hide the button. Here's an example:

css
.ui-jqgrid .ui-jqgrid-titlebar .ui-jqgrid-titlebar-close {
    display: none;
}

This CSS rule targets the expand/collapse button specifically and hides it from view. You can add this rule to your own stylesheet or include it in a <style> tag on your page.
