Overview

This is a component for creating scrolling tabs. Objectives are:

• Automatically scroll to a section by clicking on its respective tab button.
• Automatically highlight a tab button when the corresponding section is scrolled into view.
• Simple predefined styles that are easily customizable.

Installation

Peer Dependencies

As this is a React component, you must have already installed react and react-dom.

npm install react-draggable

Detailed version requirements for all dependencies:

• react >= 16.3.0
• react-dom >= 16.3.0
• react-draggable >= 4.0

Installing

After dependency installation, run the following command to install the package:

npm install scrolling-tabs

Component Structure

There are 4 components which should be structured as follows:

<ScrollingTabs>
  <Tabs>
    <Tab>First Tab</Tab>
    <Tab>Second Tab</Tab>
    ...
  </Tabs>

  <TabContext>
    First Tab context
  </TabContext>
  <TabContext>
    Second Tab context
  </TabContext>
  ...
</ScrollingTabs>

RTL

The component checks for the direction of the component, and if it is inside an RTL context (e.g., parent elements with dir='rtl'), it will render with RTL features.

You can set dir='rtl' on the document body or any parent of the <ScrollingTabs> component.

Customization

Aside from the tabColor and tabStyle props on the <ScrollingTabs> component, you can customize it by passing className and style props to <Tabs>, <Tab>, or <TabContext>.

The <Tab> component will have an active class on the selected tab. It also has two extra props: activeStyle and activeClassName, which are set only for the active tab.

Based on tabStyle and tabColor props, styles are composed in the following order:

For any Tab:

• Default styles based on tabStyle.
• Styles provided through style prop on the Tab component.

For the active Tab:

• Default styles based on tabStyle.
• Default active styles based on tabStyle.
• Styles provided through style prop on the Tab component.
• Styles provided through activeStyle prop on the Tab component.

Even with tabStyle set to none, the following styles are applied to avoid bad tab display:

{
  display: 'inline-block',
  padding-right: 15px,
  padding-left: 15px,
  margin-right: 5px,
  margin-left: 5px,
  transition: 'all .5s',
  cursor: 'pointer'
}

Responsivity

The component is responsive and will automatically scroll horizontally to the selected tab on smaller screens. If the <Tabs> component is wider than the screen, it will scroll horizontally to show all tabs.

Two arrows are displayed in the rightmost and leftmost spaces of the horizontal tabs bar. These can be removed by setting the boolean hideArrows prop to true.

Troubleshooting

If any parent element has overflow: hidden, the CSS sticky position will not work. Instead, use overflow: clip.
