WebLabel · Standard · Visual · 4 events

## Quick start

Add **Label1** in the Designer. Use the example in a page method.

```ts
Label1.caption = 'Total: $150.00';
Label1.autoSize = true;
Label1.color = '#58b9f5';
Label1.visible = true;
```

- caption and text access the same content.
- autoSize fits the dimensions to the text. Disable it for dimensions controlled by layout.
- Configure typography and color in the Inspector or style editor.

## Inspector properties

Component options and defaults. Fields without runtime access are configured in the Inspector.

| Property / source | Type and options | Default | Runtime access |
| --- | --- | --- | --- |
| `name` — Name · Identity | `string` | `—` | name |
| `x` — Left · Size & position | `number` | `0` | x |
| `y` — Top · Size & position | `number` | `0` | y |
| `width` — Width · Size & position | `number` | `80` | width |
| `height` — Height · Size & position | `number` | `24` | height |
| `itemWidth` — Responsive width · Responsive size — Fit content grows the item to its widest rendered child and preserves child intrinsic widths; minimum and maximum width remain limits. | `enum` — `fixed` `stretch` `fit-content` | `"fixed"` | Inspector / configuration |
| `itemHeight` — Responsive height · Responsive size — Fit content grows the item to its lowest rendered child and preserves child intrinsic heights; minimum and maximum height remain limits. | `enum` — `fixed` `stretch` `fit-content` | `"fixed"` | Inspector / configuration |
| `itemMinWidth` — Minimum width · Responsive size | `number` | `0` | Inspector / configuration |
| `itemMaxWidth` — Maximum width · Responsive size | `number` | `null` | Inspector / configuration |
| `itemMinHeight` — Minimum height · Responsive size | `number` | `0` | Inspector / configuration |
| `itemMaxHeight` — Maximum height · Responsive size | `number` | `null` | Inspector / configuration |
| `itemGrow` — Grow · Responsive size | `number` | `0` | Inspector / configuration |
| `itemShrink` — Shrink · Responsive size — Allows fixed and stretch flow items to yield space. Fit-content keeps its intrinsic size so its children are not compressed. | `boolean` | `true` | Inspector / configuration |
| `itemAlignSelf` — Item alignment · Responsive size — Cross-axis alignment for this item in a row or column. Auto inherits the parent alignment; responsive cross-axis stretch retains its sizing behavior. | `enum` — `auto` `start` `center` `end` `stretch` | `"auto"` | Inspector / configuration |
| `itemHorizontalAnchor` — Horizontal anchor · Anchors & offsets | `enum` — `start` `center` `end` `stretch` | `"start"` | Inspector / configuration |
| `itemVerticalAnchor` — Vertical anchor · Anchors & offsets | `enum` — `start` `center` `end` `stretch` | `"start"` | Inspector / configuration |
| `itemLeft` — Left inset · Anchors & offsets | `number` | `0` | Inspector / configuration |
| `itemRight` — Right inset · Anchors & offsets | `number` | `0` | Inspector / configuration |
| `itemTop` — Top inset · Anchors & offsets | `number` | `0` | Inspector / configuration |
| `itemBottom` — Bottom inset · Anchors & offsets | `number` | `0` | Inspector / configuration |
| `margin` — Margin · Spacing — Outer spacing on all four sides, in pixels. Row and column layouts include this spacing between components. | `number` | `0` | margin |
| `marginTop` — Margin top · Spacing — Outer spacing on this side, in pixels. Overrides the shared Margin value. | `number` | `0` — Derived from saved properties | marginTop |
| `marginRight` — Margin right · Spacing — Outer spacing on this side, in pixels. Overrides the shared Margin value. | `number` | `0` — Derived from saved properties | marginRight |
| `marginBottom` — Margin bottom · Spacing — Outer spacing on this side, in pixels. Overrides the shared Margin value. | `number` | `0` — Derived from saved properties | marginBottom |
| `marginLeft` — Margin left · Spacing — Outer spacing on this side, in pixels. Overrides the shared Margin value. | `number` | `0` — Derived from saved properties | marginLeft |
| `visible` — Visible · Behavior | `boolean` | `true` | visible |
| `collapseWhenHidden` — Collapse when hidden · Behavior — Removes the component from the layout while it is not visible. | `boolean` | `true` | collapseWhenHidden |
| `enabled` — Enabled · Behavior | `boolean` | `true` | enabled |
| `caption` — Caption · Appearance | `string` | `"Label"` | caption |
| `textWrap` — Text wrap · Appearance — None: single line. Word: between words. Break-word: also split words wider than the Label. Character: at any character. Auto Size keeps the width and fits the height when wrapping. | `enum` — `none` `word` `break-word` `character` | `"none"` | textWrap |
| `color` — Color · Appearance | `color` | `"#000000"` | color |
| `autoSize` — Auto Size · Size & position | `boolean` | `true` | autoSize |
| `currentRowBindings` — Current row · Data — Bind writable visual values to fields of this repeated row. | `current-row-bindings` — Editor: current-row-bindings | `[]` | currentRowBindings |
