glasstabs 0.1.0

Initial release.

New features

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.

glassMultiSelect() — dropdown filter with live search, select-all with indeterminate state, and three checkbox indicator styles: "checkbox", "check-only", and "filled".
glassMultiSelectServer() — typed reactive wrapper exposing selected and style reactives.
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).

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.
