This is with reference to the question I posted yesterday
Link to yesterday's post
Everything worked, But having issue breaking the rows now. As in the picture below the row "G" has "H" & "I" on the same row. Just trying how to have every alphabet and its channels on its own row. I have attached the HTML too at the bottom.
Please advise.

<div class="w3-container w3-threequarter">
<ul class="w3-ul w3-card-1" *ngFor="let head of channelDisplayHeads">
<h1 align="center" style="background-color:#0083BC;">
<font color="white">{{ head }}</font>
</h1>
<ng-container *ngFor="let channel of channelList">
<li class="list-group-item logoDisplay" *ngIf="channel.channel.substr(0, 1) === head">
<img class="w3-image" src="{{ channel.logo }}" align="center" alt="{{ channel.channel }}" width="80" height="80">
<br>
<span class="w3-left">
<mark>
<font size="1">{{ channel.cbsCode }}</font>
</mark>
</span>
<span class="w3-sand w3-right">
<font size="2">{{ channel.pickCode }}</font>
</span>
</li>
</ng-container>
</ul>
</div>
