Drop-downs provide a developer the ability to add a drop-down menu with specific properties to cells in a workbook. These drop-down menus don't require any extra code other than simply specifying which one to use for the drop-down menu.
SpreadJS has 9 different kinds of drop-downs, and this demo shows how to use the Color Picker.
You can use ColorPicker drop-down like the following code :
If you want to customize the ColorPicker, you can use these options :
colorBlockSize: number : Specify every color cell's size.
groups: IColorGroup[] : Specify the group of the color picker, every group accept a name as group name, and a color array as the group's colors.
needScaleColor: boolean : Specify whether to generate scale color group.
For example:
<template>
<div class="sample-tutorial">
<gc-spread-sheets class="sample-spreadsheets" @workbookInitialized="initSpread">
</gc-spread-sheets>
</div>
</template>
<script setup>
import '@mescius/spread-sheets-vue';
import GC from '@mescius/spread-sheets';
import { ref } from "vue";
const spreadRef = ref(null);
function initSpread(spread) {
spreadRef.value = spread;
let sheet = spread.getSheet(0);
sheet.suspendPaint();
let style = new GC.Spread.Sheets.Style();
style.cellButtons = [{
imageType: GC.Spread.Sheets.ButtonImageType.dropdown,
command: "openColorPicker",
useButtonStyle: true,
}];
sheet.setText(4, 3, "Default Color Picker");
sheet.setStyle(5, 3, style);
