如何在 mat 中使用 angular 选择嵌套值包含过滤器 [英] How to include filter in mat select nested values using angular
问题描述
我正在使用带有嵌套下拉菜单的角度材料.以父子为基础嵌套的下拉值.
I'm using angular material with nested dropdowns. The dropdown values nested with parent and child basis.
我面临两个问题.
自动建议不起作用.如果我输入父名称或其关联的子名称,则必须使用展开模式过滤并显示特定的父视图.
Auto suggestion is not working. If I type parent name or its associated child name, have to filter and show the particular parent view with expand mode.
如果我展开第一个父视图并尝试展开第二个父视图,则在展开第二个父视图时,第一个父视图应自动关闭.
If i expand first parent and trying to expand the second parent, the first parent view should close automatically while expanding the second one.
