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         


        

Answer 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>...

Answer 2

If you want to quite the icon of ion-select-option only add mode="ios" on

Answer 3

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);
      }
    });
}

Answer 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);
}
