Properties
Any property can be bound to a tag, another component's property, or a query.
| Property | Type | Default | Description |
|---|---|---|---|
value | number | 0 | The current number — reflects the handle position, and bindable. |
min | number | 0 | — |
max | number | 100 | — |
step | number | 1 | — |
showValue | boolean | true | Show the current value as a pill beside the track. |
tooltip | boolean | false | Pop a value tooltip above the handle while dragging. |
thickness | number | 4 | Track line thickness in px (default 4). |
unit | string | "" | Optional suffix shown next to the value (e.g. %, px). |
title | string | Slider | — |
showTitle | boolean | true | — |
titleSize | number | 0 | Title font size (px). 0 = follows the size. 1.0.8 |
size | enum | inherit | Field height, padding, text and title size. Project default = the project's Control size (Project settings → Theme). Use md or larger on touch panels. Options: inherit · xs · sm · md · lg · xl. 1.0.8 |
disabled | boolean | false | — |
style | style | {} | Custom CSS properties |
Events
Attach event actions to these in the Event Manager.
| Event | Label | Group | Payload |
|---|---|---|---|
click | Click | Mouse | The DOM event. |
dblclick | Double click | Mouse | The DOM event. |
contextmenu | Right click | Mouse | The DOM event. |
mouseenter | Mouse enter | Mouse | The DOM event. |
mouseleave | Mouse leave | Mouse | The DOM event. |
change | Change | Input | The DOM event. |
submit | Submit | Input | The DOM event. |
focus | Focus | Input | The DOM event. |
blur | Blur | Input | The DOM event. |
contextmenu fires your configured actions at runtime only — in LiveView and in preview. On the Designer canvas the right-click is captured to open the Event Manager, so testing it there will not run your actions. Test right-click in preview.
Notes
Bound directly to a tag, a slider writes continuously as it is dragged. Prefer binding it to a client variable and writing once, on release, through an event action.
Size New in 1.0.8
size sets the height of the slider row and the title on one scale shared by every field widget:
size | xs | sm | md | lg | xl |
|---|---|---|---|---|---|
| Field height | 28 px | 36 px | 44 px | 52 px | 64 px |
| Text | 12 px | 13 px | 14 px | 16 px | 18 px |
The default, Project default (inherit), follows the project's Control size (Project settings → Theme), so one setting resizes every field on every screen. Set size on a widget only where it has to differ. A field, a dropdown and a button at the same size line up exactly, side by side.
titleSize now defaults to 0, which follows the size. A number you set still wins.
Before 1.0.8 these widgets had one size, what is now md (a 44 px field). The project's Control size defaults to sm (36 px), sized for desktop dashboards, and every widget whose size is Project default follows it — which is every widget in an upgraded project. On a touch panel, set Project settings → Theme → Control size to md or larger: 44 px is the touch-target minimum.
