How can I show all divs at once while using ngswitchngSwitchCase?

Question

I have the following code:

  <div class="box" *ngSwitchCase="'financing'">
  <div class="box" *ngSwitchCase="'procurement'">
  <div class="box" *ngSwitchCase="'operations'">

I am using the ngSwitchCase to switch between the divs depending on what the user selects. However, I want to add one last switch case that allows the user to view all three divs at one, as follows:

 <div class="box" *ngSwitchCase="'financing'">
 <div class="box" *ngSwitchCase="'procurement'">
 <div class="box" *ngSwitchCase="'operations'">
  <div class="box" *ngSwitchCase="'summary'">

The way I have it now is that the summary part contains all the of the contents of the upper 3 divs.

How can I achieve the same case but without repeating my code?
