Is there a way to dynamically show or hide the drop-down icon depending on whether there is child data present in Angular 4? I am using rowGroup: true to group parent and child elements together.
I need the drop-down icon to be hidden when there are no children under a parent node, but visible if there is child data available.
I have attempted using a boolean variable for visibility, but it does not seem to be working as expected.
rowGroup: true,
To implement this in your HTML, consider using the following code snippet:
[class.disable]="!rowGroup"
Furthermore, make sure to add the corresponding CSS styling:
.disable{
display: none;
}
You can achieve this effect using the :only-child selector.
.dropdown-menu .caret:only-child{
display: none;
}
Hopefully this solution proves to be beneficial. Begin by verifying the presence of child data, and if any exists, update the childDataPresent variable to true.
childDataPresent: boolean = false;
rowGroup?: childDataPresent;
