unable to remove empty tag using angular 6

Here I am having a issue below is my json data

 data = {

  "required": false,

  "name": "data",

  "details": [

    {

      "name": "type",

      "details": {

        "visible": false,



      }

    },

    {

      "name": "Creation",

      "details": {



        "visible":true,



      }

    },

    {

      "name": "Creation",

      "details": {



        "visible": false,



      }

    },



    {

      "name": "Modification",

      "details": {



        "visible": true,



      }

    }



  ]

}

.html code

<ng-container *ngFor="let x of data.details">

  <ul>

  <li *ngIf="x.details.visible">             

      {{x.name}}

  </li>

  </ul>

</ng-container>

The issue here is even though I condition is true here it is creating empty tags by this my html style is getting disturbed and getting unwanted spaces

in the console it showed me like this

<ul _ngcontent-c76=""><!--bindings={

  "ng-reflect-ng-if": "false"

}--></ul>



<ul _ngcontent-c76=""><!--bindings={

  "ng-reflect-ng-if": "true"

}--><li _ngcontent-c76=""> Creation </li></ul>



<ul _ngcontent-c76=""><!--bindings={

  "ng-reflect-ng-if": "false"

}--></ul>



<ul _ngcontent-c76=""><!--bindings={

  "ng-reflect-ng-if": "true"

}--><li _ngcontent-c76=""> Modification</li></ul>

How can I remove that empty spaces.

Move the *ngIf to the ul tag.
– rrd
Nov 23 '18 at 8:17

use the ngIf condition in your ul. BTW you want so many uls? or one ul and many lis?

Nov 23 '18 at 8:17

@AshishRanjan the uls & lis are generated depending on my data if the visible is false it shouldnt display but here if it is false then it is displaying empty tags

You should change your template to following

<ul>

  <ng-container *ngFor="let x of data.details">

    <li *ngIf="x.details.visible">

      {{x.name}}

    </li>

  </ng-container>

</ul>

You would not want to have bunch of ul with single li elements. What the code above will do is to create a single ul and add some li elements within if x.details.visible condition is met
