10.7.0

React version

18.x

Language

TypeScript

Build / Runtime

Browser(s)

Steps to reproduce the behavior

Execute the Stackblitz, as an output the tabView tabs are shown unstyled.

Expected behavior

Default Tailwind style to be applied.

Still happening on the latest 10.8.2 build. I tried passing in the default tabview styling (here: https://github.com/primefaces/primereact/blob/e99a280091851ec8a80b5677ead6690edc571e78/components/lib/passthrough/tailwind/index.js#L237) manually and it also doesn't work. Any ideas on how to workaround this?

@gcko @ivanpajon need some more Tailwind expertise here.

I downloaded to local the reproducer and without any change it works fine for me.

But the fact that in the reproducer looks bad is weird... As a workaround maybe you @LB-sx @eklee can try this:

@LB-sx could it just be a StackBlitz thing with Tailwind?

Interestingly, adding 'unstyled' and the pt properties seem to work. But visually there seems to be issue when a tab is clicked: a highlighted border is drawn around the tab name (this doesn't happen on the styled theme version):

@eklee it is exactly the workaround I am using at the moment.

No I am currently prototyping a framework including PrimeReact in a R&D project, and I'm facing this issue in this project

Its weird you shouldn't have to add unstyled if you are in unstyled mode. Something has to be wrong with TabView.

@gcko any chance you can look at this one too. This is very strange.

Sure I'll check it out in a bit

Ahh, so this is related to TabView and TabPanel @melloware @eklee @LB-sx

Yea I ran into this issue back when it was first released in November, and I handled it locally. I guess I should look at addressing it directly in the PrimeReact codebase 🤔

While I am working on that, here is my current solution (in Typescript)

export const tabPanelPassThrough = (contentClassNames = '') => {
  const headerActionClassnames = (
    parent: TabViewPassThroughMethodOptions,
    context: TabViewContext,
  ) => {
    return classNames(
      'items-center cursor-pointer flex overflow-hidden relative select-none text-decoration-none user-select-none', // Flex and overflow styles.
      'border-b-2 p-2 font-medium rounded-t-lg transition-shadow duration-200 m-0', // Border, padding, font, and transition styles.
      'transition-colors duration-200', // Transition duration style.
      'focus:outline-none focus:outline-offset-0 focus:shadow-[inset_0_0_0_0.2rem_rgba(147,197,253,0.5)]', // Focus styles.
      {
        // Below are for the INACTIVE tab
        'border-slate-700 bg-blue-900 text-white/60 hover:bg-blue-900 hover:text-white/80':
          parent.state.activeIndex !== context.index, // Condition-based hover styles.
        // Below are for the ACTIVE Tab
        'bg-blue-900 border-blue-900 text-white': parent.state.activeIndex === context.index, // Condition-based active styles.
      },
    );
  };
  return {
    header: ({ props }: { props: TabPanelProps }) => ({
      className: classNames('mr-0', {
        'cursor-default pointer-events-none select-none user-select-none opacity-60':
          props.disabled,
      }), // Margin and condition-based styles.
    }),
    headerAction: ({
      parent,
      context,
    }: {
      parent: TabViewPassThroughMethodOptions;
      context: TabViewContext;
    }) => ({
      className: headerActionClassnames(parent, context),
      style: { marginBottom: '-.5rem' }, // Negative margin style.
    }),
    headerTitle: {
      className: classNames('leading-none whitespace-nowrap'), // Leading and whitespace styles.
    },
    content: {
      className: classNames(
        'bg-gray-900 p-2 border-slate-700 text-white/80 rounded-bl-2xl rounded-br-2xl',
        'overflow-y-auto scrollbar-styled',
        contentClassNames,
      ), // Background, padding, border, and text styles.
    },
  };
};

Below is a basic example of of this in use:

import { ReactNode, useMemo } from 'react';
import { TabPanel, TabView } from 'primereact/tabview';
import { tabPanelPassThrough } from 'path/to/tabPanelPassThrough';

interface TabItem {
  header: string;
  node: ReactNode;
}

export default function TDPanel(): ReactNode {
  const tabs: TabItem[] = useMemo(
    () => [
      { header: 'Risk', node: <div className="min-h-72">Risk</div> },
      { header: 'Spot', node: <div className="min-h-72">Spot</div> },
      { header: 'Loan', node: <div className="min-h-72">Loan</div> },
    ],
    [],
  );
  return (
    <div>
      <TabView>
        {tabs.map((t) => (
          <TabPanel header={t.header} key={t.header} pt={tabPanelPassThrough()}>
            {t.node}
          </TabPanel>
        ))}
      </TabView>
    </div>
  );
}

@gcko thank you a PR would be welcome!
