Hide/show individual items inside ngFor

Question

I need to show / hide part of component. Here is Angular2 example.

Answer 1

In component class, declare hideme variable (typescript):

export class MyPage{
   hideme = {};
   constructor(){
       this.hideme = {}; // init is required
   }
   ...

Show/hide control in template:

   show/hide
   
The content will show/hide

Notes: hideme not required init because hideme[item.id] is undefined thus !hideme[item.id] will true.
