关于Ag-grid Balham主题：如何完全禁用工具面板及侧边“Columns”按钮

Hey there! I’ve dealt with this exact scenario using ag-Grid’s Balham theme before, so I know how frustrating it can be to get that last "Columns" side button hidden after already disabling the tool panel. Let me share two simple, reliable ways to fix this:

Solution 1: Disable via Grid Options (Recommended) #

This is the cleanest, most maintainable approach since it uses ag-Grid’s native configuration instead of hacky CSS. The key here is controlling the sideBar property in your grid options—this manages both the side panel and its trigger button.

If you want to completely remove the entire sidebar system (button + panel), just set:

const gridOptions = {
  // Your existing grid config...
  sideBar: false, // This disables the sidebar and its trigger button entirely
};

If you ever need more granular control (e.g., keep other sidebar features but remove the "Columns" option), you can pass an empty array to sideBar—this tells ag-Grid there are no sidebar panels to show, so the button won’t render at all:

const gridOptions = {
  // Your existing grid config...
  sideBar: [], // No sidebar panels = no trigger button
};

Note: If you previously only set toolPanel: false, that hides the panel but leaves the trigger button intact. Switching to sideBar: false or sideBar: [] will take care of both.

Solution 2: CSS Override (Quick Fix) #

If you can’t modify the grid options for some reason, you can target the button directly with CSS (specific to the Balham theme):

/* Hide the "Columns" side button in Balham theme */
.ag-theme-balham .ag-side-button.ag-side-button-columns {
  display: none !important;
}

Just keep in mind this only hides the button visually—it’s still present in the DOM. For a full removal, stick with the grid options method.
