Slider

Description

The slider component is used to display and set a numerical value within a defined range of numbers, similar to the Spinner. A classic use case would be setting a dimming or volume value. The slider consists of a horizontal bar representing the range of values and a button that can be moved over it to set the current value.

<cv-slider min="0" max="100" format="%d %%">
    <cv-address transform="DPT:5.001">1/4/1</cv-address>
    <cv-icon class="decrease">ri-volume-down-line</cv-icon>
    <cv-icon class="increase">ri-volume-up-line</cv-icon>
</cv-slider>

The value range is limited by the min and max attributes. The step-width attribute can be used to specify how much the value increases/decreases when the slider is operated. The display of the value as text above the slider can be turned off with hide-value="true" and formatted using the format attribute.

To prevent every value change from being sent directly to the backend during operation and potentially overloading it, the throttle-interval attribute can be used to specify the minimum time in milliseconds that must pass between two value changes.

	value	string	Fixed value sent to this address.
	on	click, down or up	Event on which a value should be sent to this address (only useful in mode=``write or readwrite`), also needs ``value.
