Morpheus: Web Components UI Kit

Input group#

Component <neo-input-group> is a layout wrapper that flushes leading and trailing addons (text, icons, buttons) against an <input> or <neo-textinput> under one merged border. DOM order decides placement; the group owns border, radius, and focus ring so the inner field drops its own.

HTML

CSS

The selected state's markup and its scoped CSS. The CSS is wrapped in <style>@scope { ... }</style> and applies to the preview only. Edits change the preview above, applied live while Sync is on, or when you click Patch or Replace. Patch morphs the preview; Replace swaps it outright.

Signals

Datastar signals declared in the selected state's markup. Change a value to drive the preview, applied live while Sync is on, or when you click Patch.

Reference#

Slots #

Name	Description
default	An `<input>` or `<neo-textinput>`, paired with optional addons.

`span / neo-kbd / neo-kbd-group`	A direct passive text, unit, or shortcut addon.

CSS variables #

Name	Default	Description
`--neo-input-group-addon-padding`	`0 0.6rem`	Inline padding of text and button addons.
`--neo-input-group-addon-bg`	`color-mix(in srgb, var(--page-fg) 4%, transparent)`	Background fill distinguishing addons from the input surface.

Examples#

Currency prefix#

A direct <span> addon gets a muted background while the group keeps one shared outer border. Click the addon and the caret lands in the input.

Username + domain#

Drop a <neo-combobox> in as a trailing addon to let the user pick from a short list of domains. The combobox's trigger adopts the addon background via a small demo-only override.

HTML

Templ

Range bounds#

Several addons at once: a <neo-toggle> flipping between min and max on the left, a stack of <neo-select>s on the right (mass unit + rate denominator). The inner input takes the remaining horizontal space.

Templ

Comparison#

A <neo-select> of comparison operators sits between two number-only <neo-textinput> fields, composing one condition. The operator is a fixed glyph-width column that opens on hover; the operands share the rest.

HTML

Templ

Search#

A direct <neo-icon> addon is recognized automatically and stays flush with no separator, leaving the icon as a subtle inline mark.

Search with shortcut#

Combine an icon addon with a trailing pair of <neo-kbd> chips inside a text addon.

HTML

Templ

Search with submit#

Pair an input with an action button (copy, submit, toggle visibility…). A direct <neo-button> automatically drops its border and radius so it sits flush.

HTML

Templ

A window menubar: each <neo-button> opens a <neo-menu> dropdown and the group merges them under one border.

Disabled#

When the inner input goes disabled, the group mirrors that to its own aria-disabled and the whole assembly fades together.
