Slider

The Slider component allows users to select a numeric value from a specified range by dragging a handle along a track.

Usage

To use the Slider component, specify the minimum (min), maximum (max), initial value (value), and step size (step).

import Slider from '@components/Basic/Slider/Slider';

const App = () => {
    return (
        <>
            <Slider min={0} max={100} value={35} step={1} />
        </>
    );
};

export default App;

Caution

The thumb of the slider won’t be displayed by default. To enable it provide the Thumb slot inside the Slider component.

Slider.Grid

The Slider.Grid slot displays a visual indicator of progress along the slider’s range, dividing the track into evenly spaced segments called “pols.” Each pol marks a separation between the minimum and maximum values, helping users see how far the current value has moved.

You can control the number of main pols (with value labels) using the pols prop.
Additionally, by enabling the pols-without-text prop, smaller unlabeled pols are rendered between the main pols for finer granularity and enhanced visual feedback.

Properties

Prop Name	Type	Default	Description
style	JSX.CSSProperties	{}	Inline styles to apply directly to the grid container.
class	string	""	Additional CSS classes to style the grid container.
pols	number	5	Number of main pols (segments with value labels) to display along the slider track.
pols-without-text	number	5	If prop is present, it renders smaller unlabeled pols between main pols for finer granularity.
pol-style	JSX.CSSProperties	{}	Inline styles to apply directly to each pol (segment marker).
pol-class	string	""	Additional CSS classes to style each pol (segment marker).
pol-value-style	JSX.CSSProperties	{}	Inline styles for poles displaying the slider’s current value.
pol-value-class	string	""	Additional CSS classes for poles displaying the slider’s current value.

Usage

import Slider from '@components/Basic/Slider/Slider';

const App = () => {
    return (
        <>
            <Slider min={0} max={100} value={35} step={1}>
               <Slider.Grid pol-style={{'background-color': 'red', 'color': 'green'}} pols={5} pols-without-text={7} />
            </Slider>
        </>
    );
};

export default App;

Caution

The Slider.Grid slot will only be rendered if you include it as a child of the Slider component.

Guide

Retrieve and use the slider value

• To get the current value of the Slider component, use the onChange prop.

Steps

1. Define a state variable (e.g., using createSignal) to store the slider value.
2. Pass a callback to the onChange prop that updates this state variable.
3. Use the state variable wherever you need the slider’s value.

import Slider from '@components/Basic/Slider/Slider';
import { createSignal} from 'solid-js';

const App = () => {
    const [sliderValue, setSliderValue] = createSignal(50);

    return (
        <>
            <Slider onChange={(value) => setSliderValue(value)} value={50} max={100} min={0} step={1} />
            <div>{sliderValue()}</div>
        </>
    );
};

export default App;

Set the value of the slider programmatically

The Slider component lets you set the value through code.

Steps

1. Declare a ref variable with type SliderRef and pass it to the Slider component.
2. Call ref.changeValue() from anywhere (e.g., a keyboard event or external button) to set the value programmatically.

import Slider { SliderRef } from '@components/Basic/Slider/Slider';

const App = () => {
    let sliderRef!: SliderRef;

    const handleKeyPress = (e: KeyboardEvent) => {
        if (e.keyCode !== 13) return

        sliderRef.changeValue(100);
    }

    return (
        <>
            <Slider value={50} max={100} min={0} step={1} />
        </>
    );
};

export default App;

Customizing grid pols

You can customize the grid pols that display values using the pol-value-style and pol-value-class properties of the Slider.Grid slot.

This is particularly useful for adjusting the font size, width, or text wrapping behavior of the pol value elements.

By default, the text wraps to break words based on the width of the pol value element.

In the following example, you can see how to modify the font size, width, and disable the overflow-wrap property for the pol value elements.

import Slider from '@components/Basic/Slider/Slider';
const App = () => {
    return (
        <Slider min={0} max={100} value={35} step={1}>
            <Slider.Grid pol-value-style={{'font-size': '0.9vmax', width: '1.5vmax', 'overflow-wrap': 'normal'}} pol-value-class="custom-pol-value" />
        </Slider>
    );
};
export default App;
