TsgcHTMLComponent_Offcanvas — render a Bootstrap 5 off-canvas slide-in panel from the start, end, top or bottom edge, with an optional dark theme and static backdrop, in Delphi, C++ Builder and .NET.
A slide-in panel component that emits Bootstrap 5 offcanvas markup. Choose a placement edge, set the title and body, then read the HTML property — or call the static Build helper for a one-liner.
TsgcHTMLComponent_Offcanvas
Bootstrap 5 offcanvas markup
Delphi, C++ Builder, .NET
Call Build(id, title, body, placement, dark) for a quick panel, or create the component, set Placement and Dark, then read HTML. Pair it with BuildTriggerButton to open the panel.

Title sets the header heading and Body holds the panel content; OffcanvasID is the element id referenced by triggers.
Placement slides the panel from opStart, opEnd, opTop or opBottom via TsgcHTMLOffcanvasPlacement.
Dark applies the dark color scheme (and a white close button); CSSClass appends extra classes to the panel.
StaticBackdrop keeps the panel open on an outside click; ShowClose toggles the header close button.
Build(id, title, body, placement, dark) returns a ready panel; BuildTriggerButton(offcanvasID, text, style) emits a button that opens it.
HTML returns the complete Bootstrap offcanvas markup — serve it, or assign it to a page template's BodyContent.
