HTML选择下拉菜单自定义箭头CSS [英] HTML select dropdown custom arrow css

问题描述

我试图将自定义箭头用于代码中提到的下拉菜单.我在这里面临两个问题.

I am trying to use a custom arrow for a dropdown menu as mentioned in the code. I am facing two issues here.

1.无法将箭头部分放置在下拉菜单旁边.

1.unable to place the arrow section adjacent to the dropdwon.

2.此自定义箭头不可单击.

2.This custom arrow is not clickable.

如何实现这两个目标?

我尝试在:after 部分中使用 z-index; -1 .但是它没有按预期工作.

I tried to use z-index;-1 for the :after section. But its not working as expected.

	 
.expenses_div {
	
	width:90% !important;
	margin:auto;
	margin-top:2%;
