glasstabs 0.2.1

New features

Tab widget

• Added updateGlassTabsUI() for programmatic tab switching from the server.
• Added showGlassTab() and hideGlassTab() for dynamically showing and hiding tabs at runtime.
• Added appendGlassTab() and removeGlassTab() for adding and removing tabs at runtime.

Improvements

• glassTabsUI() now validates selected against the available glassTabPanel() values and errors early on invalid tab ids.
• The tab widget now reports its initial active tab to Shiny immediately after session startup, so glassTabsServer() is populated on first render.
• Added ARIA roles and selected-state attributes to tab navigation markup.
• Improved tab re-initialization and transition handling for dynamic tab changes, including show/hide, append/remove, and rapid successive updates.
• Improved halo and transfer-trace positioning after runtime tab layout changes.

Bug fixes

• Opening a dropdown now closes any other open glasstabs dropdown, fixing a visual stacking issue where multiple dropdowns appeared simultaneously.

• Improved widget lifecycle in dynamic UI (renderUI(), conditionalPanel()). Widgets initialize more reliably and clean up properly when removed.

• Widgets now emit their initial value to Shiny immediately after rendering, fixing timing issues with conditionalPanel() and dynamic UI.

Internal improvements

• JavaScript engine refactored to use internal state instead of DOM scanning. No changes to the R API — all existing code works without modification.

• Added scroll containers for long option lists, debounced search, and .gt-loading / .gt-disabled CSS utility classes.

Documentation

• Added a dedicated cheatsheet vignette for common widget patterns and server-side helpers.
• Added a smoke-test example app covering programmatic tab switching, dynamic tab visibility, runtime tab insertion/removal, and rapid interaction paths.
• Expanded README and pkgdown navigation to surface the new server-side tab controls and cheatsheet more clearly.

glasstabs 0.1.1

New features

Single-select widget

• Added glassSelect(), an animated single-select dropdown for Shiny.
• Added updateGlassSelect() for server-side updates to choices and selection.
• Added glassSelectValue() as a convenience reactive helper for reading the selected value.

Multi-select widget

• Added updateGlassMultiSelect() for server-side updates to choices, selection, and checkbox style.
• Added glassMultiSelectValue() as a convenience reactive helper for reading selected values and active style.
• Added optional label support to glassMultiSelect().
• Added configurable all_label support to control the trigger text shown when all choices are selected.

Improvements

• Aligned glassSelect() and glassMultiSelect() more closely with standard Shiny input behavior.
• Added client-side input bindings so select widgets now support session$sendInputMessage() update patterns.
• Preserved current glassMultiSelect() default behavior where selected = NULL initializes all choices as selected.
• Improved choice normalization so named choices retain display labels correctly.
• Improved hue normalization for the "filled" multi-select style.
• Updated vignettes and examples to show direct Shiny input usage and server-side update patterns.

Documentation

• Added a new vignette for glassSelect().
• Updated the getting started vignette to include glassSelect().
• Updated the multi-select vignette to document updateGlassMultiSelect() and glassMultiSelectValue().

Internal changes

• Added tests for glassSelect(), updateGlassSelect(), and glassSelectValue().
• Expanded tests for glassMultiSelect() server-side updates and helper utilities.

glasstabs 0.1.0

Initial release.

New features

Tab widget

• glassTabsUI() — animated glassmorphism-style tab navigation with a sliding glass halo and transfer trace between tabs.
• glassTabPanel() — defines a single tab button and its content pane.
• glassTabsServer() — reactive helper that tracks the active tab value.
• glass_tab_theme() — custom color theme for glassTabsUI() with eight independent handles: tab_text, tab_active_text, halo_bg, halo_border, content_bg, content_border, card_bg, card_text.
• Built-in "dark" (default) and "light" presets for glassTabsUI().
• Keyboard navigation using the Left and Right arrow keys.
• Full bs4Dash compatibility via wrap = FALSE.

Multi-select filter widget

• glassMultiSelect() — dropdown filter with live search, select-all with indeterminate state, and three checkbox indicator styles: "checkbox", "check-only", and "filled".
• glassFilterTags() — tag-pill display area that stays in sync with a glassMultiSelect() automatically via JavaScript; clicking × on a pill deselects that option.
• glass_select_theme() — custom color theme with four handles: bg_color, border_color, text_color, accent_color.
• Built-in "dark" and "light" presets for glassMultiSelect().
• show_style_switcher, show_select_all, show_clear_all flags to hide UI chrome (all default TRUE).
• Per-option HSL hue angles for the "filled" style via the hues argument (auto-assigned if omitted).

General

• useGlassTabs() — injects CSS and JavaScript via htmltools::htmlDependency, which is deduplicated automatically by Shiny.
• All theming uses pre-computed CSS variables (no color-mix()), ensuring compatibility with Shiny’s embedded browser.
• Multiple instances of either widget on the same page work independently; each instance is scoped to its own id.
