How to make a hidden CheckBox depending on a selection?

Question

Angular

There are 4 CheckBoxes:
1.Wood
2.Metal
3.Oak
4.Aluminum
Wood
Metal
Oak
Aluminum
When you click Wood, the Aluminum CheckBox disappears. How can this be implemented?

Answer 1

<input type="checkbox" ng-model="tree">

<input type="checkbox" ng-model="aluminium" ng-if="!tree">

If you need it not to disappear from the DOM, but to hide and save the value, then use ng-show
