Appends HTML content to an element, preserving existing content. Similar to Append() but takes an explicit element parameter.

Syntax

MaterialSB::AddContent(Element, Content.s)

Parameters

Element	The DOM element to append content to.
Content.s	The HTML content string to append.

Return Value

None.

Remarks

This function uses insertAdjacentHTML('beforeend', ...) to append content at the end of the element, preserving existing children.

The difference from Append() is that AddContent() requires an explicit element parameter, while Append() uses the current parent from the stack.

Example

Global logContainer, messageCount = 0

Procedure AddLogMessage()
  messageCount + 1
  MaterialSB::AddContent(logContainer, MaterialSB::Paragraph("[" + FormatDate("%hh:%ii:%ss", Date()) + "] Log message #" + Str(messageCount), MaterialSB::#Color_Grey))
EndProcedure

Procedure AddWarning()
  messageCount + 1
  MaterialSB::AddContent(logContainer, MaterialSB::Paragraph("[" + FormatDate("%hh:%ii:%ss", Date()) + "] Warning #" + Str(messageCount), MaterialSB::#Color_Orange))
EndProcedure

Procedure AddError()
  messageCount + 1
  MaterialSB::AddContent(logContainer, MaterialSB::Paragraph("[" + FormatDate("%hh:%ii:%ss", Date()) + "] Error #" + Str(messageCount), MaterialSB::#Color_Red))
EndProcedure

Procedure Main(Success)
  If Success
    MaterialSB::Row(MaterialSB::#Grid_Container)
      MaterialSB::Col(12)
        MaterialSB::Card()
          logContainer = MaterialSB::CardContent()
            MaterialSB::Append(MaterialSB::Header("Log Output", 4))
            MaterialSB::Append(MaterialSB::Paragraph("Messages will appear below:", MaterialSB::#Color_Grey))
          MaterialSB::CloseCurrentParent()
          MaterialSB::CardAction()
            MaterialSB::Button("Add Log", @AddLogMessage())
            MaterialSB::Button("Add Warning", @AddWarning(), MaterialSB::#Button_Outlined)
            MaterialSB::Button("Add Error", @AddError(), MaterialSB::#Button_Outlined)
          MaterialSB::CloseCurrentParent()
        MaterialSB::CloseCurrentParent()
      MaterialSB::CloseCurrentParent()
    MaterialSB::CloseCurrentParent()
  EndIf
EndProcedure
