This plugin enables you to add a configurable dropdown menu to the table's column headers.
The dropdown menu acts like the Context Menu but is triggered by clicking the button in the header.
To use the default dropdown contents, set it to true, or to customize it by setting it to use a custom list of actions. For the available entry options reference, see the Context Menu demo.
const container = document.querySelector('#example2');const hot =newHandsontable(container,{data: Handsontable.helper.createSpreadsheetData(3,7),colHeaders:true,licenseKey:'non-commercial-and-evaluation',height:'auto',dropdownMenu:['remove_col','---------','make_read_only','---------','alignment']});
