Tab Navigation always active


Topic: Tab Navigation always active

Christian Aichner pro premium asked a week ago

Describe the bug

All navigation links of all MDBNav pills are active, no matter the active prop given to MDBNavLink


My code:

<MDBNav pills color="primary" className="flex-column">
{, key) => {
        <MDBNavItem key={key}>
            active={this.state.activeItemInnerPills === key} 
            <MDBIcon icon={setting.icon} className="mr-2" /> {setting.title}

Regarding to this code, the class active should only be given, if this.state.activeItemInnerPills === key - which works perfectly fine.

A quick console.log confirms this:

However, the tab looks like this:

enter image description here

As you can see, every tab is active.

Taking a look at the HTML, the following sight worries me:

enter image description here

It looks like every navigation button is already active, and the active param only adds one additional active.

Expected behavior

Only the active item should have a class active.

Additional information

You can find the entire code on GitHub.

Checking MDB code for bug

I have no idea about the origin of this problem. According to the NavLink.js file in our GitLab, there should be no problem:

const { children, className, disabled, active, to, ...attributes } = props;
  const classes = classNames(
    disabled ? 'disabled' : 'Ripple-parent',
    active && 'active',

Therefore, "active" should only be a class, if the parameter active is true.

Cheers, Chris

A temporary fix would be to remove all active classes using JavaScript, and then setting the active manually. This can be achieved by using React DOM References (like Ref={this.tab1}) and then removing all classes using removeAttribute("class") on this reference. Then setting the previous classes + active if used.

Best regards, Chris

@Jakub Chmura you already know the origin of the bug? You need any assistance in solving?

Hi @Christian Aichner,

We know what's wrong with tabs/pills... components but we need to implement and test this fix. In this case, there was a problem with the react-router library. We've found that the problem only occurs locally. If you put the project on the web, everything should be ok.

We're currently working to resolve the issue. If your solution doesn't break anything in your project, you can use it until our fix.

Best regards,
