Hello! I cannot recreate the problem you are experiencing. Could you please prepare a snippet (top right of the write post box) or pass the code here as a text? If you wish to upload, you can use mdbgo to publish your project.

Are you installing our package via npm or any other way? Best Regards!

We've tried the "get started" project in your doc, add MDB with the command "vue add mdb5" and add the dropdown like this:

<MDBContainer>

  <MDBDropdown v-model="dropdown1">
<MDBDropdownToggle @click="dropdown1 = !dropdown1">
  Dropdown button
</MDBDropdownToggle>
<MDBDropdownMenu aria-labelledby="dropdownMenuButton">
  <MDBDropdownItem href="#">Action</MDBDropdownItem>
  <MDBDropdownItem href="#">Another Action</MDBDropdownItem>
  <MDBDropdownItem href="#">Something else here</MDBDropdownItem>
</MDBDropdownMenu>

  <div
    class="d-flex justify-content-center align-items-center"
    style="height: 100vh"
  >
    <div class="text-center">
      <img
        class="mb-4"
        src="https://mdbootstrap.com/img/logo/mdb-transparent-250px.png"
        style="width: 250px; height: 90px"
      />
      <h5 class="mb-3">{{ msg }}</h5>
      <p class="mb-3">MDB Team</p>

Could you provide your vue-cli ( vue --version in terminal ) and node ( node --version ) version ? Have you tried installing our package via npm to see if you have the same problem?

The only thing I can see is that the closing MDBDropdown tag is missing in the code you showed above.


Kiril priority commented 1 month ago

vue-cli version: 5.0.8 node version: 16.13.2 The closing tag is there in the project, it's the cut and paste that didn't paste it. To reproduce, you have to rapidly do multiple clicks on the dropdown button, I mean VERY rapidly and A LOT of clicks. Once the bug appears, the dropdown stops working. We didn't find this until one of our QA testers tried the sample. We have a QA team testing everything very thoroughly! I can send you the zip project and a video of the bug by email if you want.


Bartosz Cylwik staff commented 1 month ago

Ok, now I can see the issue. I wasn't fast enough with the clicks. We have added this to our to do list. Thank you for your feedback!


Kiril priority answered 1 month ago


Hi, we've created a basic app following the "get started" on your site. We've added a MDBDropdown and if we click rapidly on the button, it crashes, see the picture below. Is there somewhere we can upload the project for you to investigate? enter image description here

Hello! Could you give us more info about your problem (template, screenshots or snippet)? Best Regards!
