This is the forum for the yii2-slider extension for Yii framework 2.0. This is an advanced slider input for Yii Framework 2 based on bootstrap-slider plugin. Allows vertical or horizontal orientation of slider, setup min/max values and step, range selector (multiple handles to control the range), three shapes for handles, touch capablity and support for touch devices and more.
You could easily add a text box and trap two change events (of the hidden input and of the displayed input) - to update your use case.
You can also try the RangeInput widget from the yii2-widgets stable, which offers what you need by default (it uses HTML 5 range input). You can update with the slider as well as the input.
