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:
import { Component, NgModule, enableProdMode } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { SpreadSheetsModule } from '@mescius/spread-sheets-angular';
import GC from '@mescius/spread-sheets';
import './styles.css';
@Component({
selector: 'app-component',
templateUrl: 'src/app.component.html'
})
export class AppComponent {
hostStyle = {

height: '100%',
overflow: 'hidden',
float: 'left'
};
constructor() {
}
initSpread($event: any) {
let spread = $event.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);
