Tab groups organise content into a container that shows one section at a time.

This component makes use of tabs and tab panels. Each tab must be slotted into the navigation slot and its panel must refer to a tab panel of the same name.

<pc-tab-group>    <pc-tab slot="navigation" panel="general">General</pc-tab>    <pc-tab slot="navigation" panel="custom">Custom</pc-tab>    <pc-tab slot="navigation" panel="advanced">Advanced</pc-tab>    <pc-tab slot="navigation" panel="disabled" disabled>        Disabled    </pc-tab>    <pc-tab-panel name="general">        This is the general tab panel.    </pc-tab-panel>    <pc-tab-panel name="custom">        This is the custom tab panel.    </pc-tab-panel>    <pc-tab-panel name="advanced">        This is the advanced tab panel.    </pc-tab-panel>    <pc-tab-panel name="disabled">        This is a disabled tab panel.    </pc-tab-panel></pc-tab-group>

Fixed scroll controls

When tabs are scrolled all the way to one side, the scroll button on that side isn’t visible. Set the fixed-scroll-controls to always show both scroll buttons.

Manual activation

When focused, keyboard users can press ← and → to select the desired tab. By default, the corresponding tab panel will be shown immediately (automatic activation). You can change this behaviour by setting activation="manual" which will require the user to press Space or Enter before showing the tab panel (manual activation).

<pc-tab-group activation="manual">    <pc-tab slot="navigation" panel="general">General</pc-tab>    <pc-tab slot="navigation" panel="custom">Custom</pc-tab>    <pc-tab slot="navigation" panel="advanced">Advanced</pc-tab>    <pc-tab slot="navigation" panel="disabled" disabled>        Disabled    </pc-tab>    <pc-tab-panel name="general">        This is the general tab panel.    </pc-tab-panel>    <pc-tab-panel name="custom">        This is the custom tab panel.    </pc-tab-panel>    <pc-tab-panel name="advanced">        This is the advanced tab panel.    </pc-tab-panel>    <pc-tab-panel name="disabled">        This is a disabled tab panel.    </pc-tab-panel></pc-tab-group>
