The QSlider is a great way for the user to specify a number value between a minimum and maximum value, with optional steps between valid values. The slider also has a focus indicator (highlighted slider button), which allows for keyboard adjustments of the slider.
Also check its “sibling”, the QRange component.
Usage
WARNING
You are responsible for accommodating the space around QSlider so that the label and marker labels won’t overlap the other content on your page. You can use CSS margin or padding for this purpose.
Standard
Vertical
With inner min/max v2.4+
Sometimes you need to restrict the model value to an interval inside of the track’s length. For this purpose, use inner-min and inner-max props. First prop needs to be higher or equal to min prop while the latter needs to be lower or equal to the max prop.
With step
The step property can also be floating point number (or numeric 0 if you need infinite precision).
With label
In the example below, move the slider to see the label.
The example below is better highlighting how QSlider handles label positioning so that it always stays inside the QSlider’s box horizontally.
Markers
Marker labels v2.4+
TIP on slots
In order to use the marker label slots (see below), you must enable them by using the marker-labels prop.
Other customizations v2.4+
Lazy input
Null value
Reverse
Force dark mode
Readonly and disable
With QItem
Native form submit
When dealing with a native form which has an action and a method (eg. when using Quasar with ASP.NET controllers), you need to specify the name property on QSlider, otherwise formData will not contain it (if it should):
