Hi,
I would like to format the dropdown menu and I was trying to edit the color of the checkbox when it’s filled with the following in CSS file:
.handsontable .htCheckboxRendererInput {
background-color: #18423b;
}
Unfortunately, this didn’t do anything. Also I would like to find out how the width of the dropdown menu could be changed?
Thanks!
Hi @roxana.tugulea
Checkboxes are styled by the browser. Here’s a good article on that Pure CSS Custom Checkbox Style | Modern CSS Solutions
We do not add any additional styling for this element other than simple alignment within the TD element

Thanks for the tip! Managed to do it. 
Great! I’m happy to hear that. I will close the thread. But feel free to open a new one when needed.
