How to generate the menu recursive RAZOR pages-CodePudding

As title, I want to razor page generated tree menu, the following database data

 
ID MENU_NAME PARENT_ID URL ICON ORDER 
Zero NULL NULL system 1 
Other NULL NULL set 1 2 
3 1 User/User management Index NULL 3 
4 test set 2 OtherTest/Index NULL 4

The following code is the code for the front desk, but can only generate 2 levels of menus, cannot generate multi-stage, a great god give a idea how to generate multilevel menu

 
@ the if (menus!=null) 
{
Foreach (var module in menus. OrderBy (x=& gt; X.o. RDER.) Where (o=& gt; O.P ARENT_ID=="0")) 
{
 
 
 
 
 
@ foreach (var menu in menus. OrderBy (x=& gt; X.o. RDER.) Where (item=& gt; Item. The PARENT_ID==module. ID)) 
{
 
 
@ menu. MENU_NAME 
 
 
} 
 

 
} 
}

You the @ foreach is not necessary to write, control directly recursive call myself to go,
