How to remove small caret from ion-select in ionic4

Question

I want to remove the inbuilt grey small caret from ion-select, and use my custom caret(arrow) instead.

Code:

ion-select {
  color: grey;
  background:url("/assets/resources/img/ArrowDownConfig.svg");
}

But my css code is unable to precedence over the ionic(inbuilt).

You can see there are two arrows in the image, one is inbuilt and another is custom. I want to remove inbuilt(ionic) one.

Solution 1

I've created this directive which you can add to your ion-select to make it look just like other ion elements with placeholder (without arrow).

Usage:

<ion-select placeholder="Choose" appNoArrow>...

Solution 2

To remove the icon,

 ion-select::part(icon) {
    display: none !important;
   }

To modify the icon,

  ion-select::part(icon) {
    color: #ffa612 !important;
   }

Solution 3

If you want just remove the carets, you can do this:

// ...other page methods

  ionViewDidEnter() {
    const ionSelects = document.querySelectorAll('ion-select');
    ionSelects.forEach((sel) => {
      sel.shadowRoot.querySelectorAll('.select-icon-inner')
        .forEach((elem) => {
          elem.setAttribute('style', 'display: none;');
        });
    });
  }

Based on @Sangminem response

In addition, in my case, I'm using slot="end" with an ion-icon to place a replacement icon:

<ion-item lines="inset">
  <ion-label position="floating">Label</ion-label>

  <ion-select>
    <ion-select-option value="1">Option 1</ion-select-option>
    <ion-select-option value="2">Option 2</ion-select-option>
    <ion-select-option value="2">Option 3</ion-select-option>
  </ion-select>

  <ion-icon color="danger" slot="end" name="arrow-dropdown-circle" class="ion-align-self-center"></ion-icon>
</ion-item>

Solution 4

I don't know how to fix, faced same problem, but it seems to be issue with DOM Shadow

If you will find anything, let to know as well please, thanks.

Update: Found some answer

UPDATE #2

I created directive in order to have access to Shadow DOM and it's able to add styles into isolated DOM.

HTML:

 <ion-select appStyle>

Directive(need to find better implementation):

    constructor(private el: ElementRef) {

    setTimeout(() => {
        this.el.nativeElement.shadowRoot.querySelector('.select-icon-inner').setAttribute('style', 'display: none !important');
    }, 3000);
}

Solution 5

If there are several ion-select items, here is a sample.

TS Code :

ionViewDidEnter() {
    // ion-select customizing
    const ionSelects = document.querySelectorAll('ion-select');
    let img = null;
    ionSelects.forEach((ionSelect) => {
      const selectIconInner = ionSelect.shadowRoot.querySelector('.select-icon').querySelector('.select-icon-inner');
      if(selectIconInner){
        selectIconInner.attributes.removeNamedItem("class");
        img = document.createElement("img");
        img.src = "./new-arrow-down-image.svg";
        img.style.width = "12px";
        img.style.paddingTop = "3px";
        img.style.paddingLeft = "4px";
        img.style.color = "black";
        img.style.opacity = "0.5";
        selectIconInner.appendChild(img);
      }
    });
}

Yeah, this is working for Ionic 5. Actually I am using "@ionic/angular": "^5.0.4" and it's working fine.

I meant... That this doesn’t work for Ionic 4 or less. Only does for Ionic 5 or more.

BTW, if you use a floating label, you should use width: 0 instead of display:none

For Ionic 5, you should use this answer instead: stackoverflow.com/a/62851330/7242535
