Clicking radio button does not pop up ion-select

Hi all,

I am trying to select options after clicking the branch radio button. Issues are:

  1. Clicking radio icon only marks the option selected but does not pop up the select options
  2. Clicking the label pops up the select options but does not markthe radio selected

How can I make the select option pop up, regardless of where I click and the radio is selected as well?

<ion-item>
    <ion-radio item-left value="me"></ion-radio>
    <ion-label>Me</ion-label>
</ion-item>
<ion-item>
    <ion-radio item-left value="branch"></ion-radio>
    <ion-label>Branches</ion-label>
    <ion-select [(ngModel)]="branches" multiple="true">
        <ion-option>Branch 1</ion-option>
        <ion-option>Branch 2</ion-option>
        <ion-option>Branch 3</ion-option>
    </ion-select>
</ion-item>
