Topic: MDBAutocomplete dropdown in a modal displayed behind the modal

Lukasz S free asked 3 years ago


Expected behavior

Using MDBootstrap 5 React, when embedding a MDBAutocomplete inside an MDBModal, once I start typing, I should be able to see the options in the autocomplete and select them by clicking on one of the options

Actual behavior

autocomplete options hidden behind the modal

The autocomplete suggestions are displayed behind the modal, and are greyed out, so it's not possible to see the options.

When I look at the resulting HTML, I can see that the autocomplete DIV is added at the bottom of the tag, rather than within the modal itself, and it has the z-index set to 1000, which seems to be not enough.

<div class="autocomplete-dropdown-container" style="position: absolute; z-index: 1000; inset: 0px auto auto 0px; transform: translate(0px, 673px); width: 100%;" data-popper-reference-hidden="false" data-popper-escaped="false" data-popper-placement="bottom-start">
   <div class="autocomplete-dropdown open">
      <ul class="autocomplete-items-list" role="listbox" style="max-height: 190px;">
         <li class="autocomplete-item" role="option">One</li>
            ...
         <li class="autocomplete-item" role="option">Eight</li>
      </ul>
   </div>
</div>

I "fixed" it by adding the following to my CSS:

div.autocomplete-dropdown-container {
  z-index: 15000 !important;
}

But I'm sure there's a proper way to fix it. Is this a bug in MDBootstrap or something I'm doing wrong?

Resources (screenshots, code snippets etc.)

After I had the issue in my own code, I tried reproducing it again and took the most basic examples from your website, combining the MDBModal and MDBAutocomplete into one file.

Here's the code I have:

import React, { useState } from "react";

import {
  MDBBtn,
  MDBModal,
  MDBModalDialog,
  MDBModalContent,
  MDBModalHeader,
  MDBModalTitle,
  MDBModalBody,
  MDBModalFooter,
  MDBAutocomplete,
} from "mdb-react-ui-kit";

function ModalTest() {
  const [centredModal, setCentredModal] = useState(false);

  const toggleShow = () => setCentredModal(!centredModal);

  const [basicValue, setBasicValue] = useState("");
  const data = ["One", "Two", "Three", "Four", "Five", "Six", "Seven", "Eight"];

  return (
    <>
      <MDBBtn onClick={toggleShow}>Vertically centered modal</MDBBtn>
      <MDBModal
        tabIndex="-1"
        show={centredModal}
        getOpenState={(e) => setCentredModal(e)}
      >
        <MDBModalDialog centered>
          <MDBModalContent>
            <MDBModalHeader>
              <MDBModalTitle>Modal title</MDBModalTitle>
              <MDBBtn
                className="btn-close"
                color="none"
                onClick={toggleShow}
              ></MDBBtn>
            </MDBModalHeader>
            <MDBModalBody>
              <MDBAutocomplete
                inputValue={basicValue}
                setInputValue={setBasicValue}
                label="Example label"
                dataFilter={(value) => {
                  return data.filter((item) => {
                    return item.toLowerCase().startsWith(value.toLowerCase());
                  });
                }}
              />
            </MDBModalBody>
            <MDBModalFooter>
              <MDBBtn color="secondary" onClick={toggleShow}>
                Close
              </MDBBtn>
              <MDBBtn>Save changes</MDBBtn>
            </MDBModalFooter>
          </MDBModalContent>
        </MDBModalDialog>
      </MDBModal>
    </>
  );
}

export default ModalTest;

Hi!

Yes, that's a bug. This temporary solution is fine, but we have to fix it at the core of the MDBAutocomplete component in the next release :)

Keep coding!

Hi Krzysztof,

That's great, thanks for confirming, looking forward to the fix, for now I'll just use the temporary fix instead.

Pozdrawiam, Lukasz
