An HTML editor component based on Suneditor.

import reflex as rx


class EditorState(rx.State):
    content: str = "<p>Editor content</p>"

    def handle_change(self, content: str):
        """Handle the editor value change."""
        self.content = content


def editor_example():
    return rx.vstack(
        rx.editor(
            set_contents=EditorState.content,
            on_change=EditorState.handle_change,
        ),
        rx.box(
            rx.html(EditorState.content),
            border="1px dashed #ccc",
            border_radius="4px",
            width="100%",
        ),
    )

The extended options and toolbar buttons can be customized by passing an instance of rx.EditorOptions for the set_options prop.

The button_list prop expects a list of lists, where each sublist contains the names of buttons forming a group on the toolbar. The character "/" can be used in place of a sublist to denote a line break in the toolbar.

Some valid button_list options are enumerated in rx.EditorButtonList, seen below.

class EditorButtonList(list, enum.Enum):
    BASIC = [
        ["font", "fontSize"],
        ["fontColor"],
        ["horizontalRule"],
        ["link", "image"],
    ]
    FORMATTING = [
        ["undo", "redo"],
        [
            "bold",
            "underline",
            "italic",
            "strike",
            "subscript",
            "superscript",
        ],
        ["removeFormat"],
        ["outdent", "indent"],
        ["fullScreen", "showBlocks", "codeView"],
        ["preview", "print"],
    ]
    COMPLEX = [
        ["undo", "redo"],
        ["font", "fontSize", "formatBlock"],
        [
            "bold",
            "underline",
            "italic",
            "strike",
            "subscript",
            "superscript",
        ],
        ["removeFormat"],
        "/",
        ["fontColor", "hiliteColor"],
        ["outdent", "indent"],
        ["align", "horizontalRule", "list", "table"],
        ["link", "image", "video"],
        ["fullScreen", "showBlocks", "codeView"],
        ["preview", "print"],
        ["save", "template"],
    ]

A custom list of toolbar buttons may also be specified using these names as seen in the following example.

Since this example uses the same state as above, the two editors contents are shared and can be modified by either one.

rx.editor(
    set_contents=EditorState.content,
    set_options=rx.EditorOptions(
        button_list=[
            ["font", "fontSize", "formatBlock"],
            ["fontColor", "hiliteColor"],
            [
                "bold",
                "underline",
                "italic",
                "strike",
                "subscript",
                "superscript",
            ],
            ["removeFormat"],
            "/",
            ["outdent", "indent"],
            ["align", "horizontalRule", "list", "table"],
            ["link"],
            ["fullScreen", "showBlocks", "codeView"],
            ["preview", "print"],
        ]
    ),
    on_change=EditorState.handle_change,
)

See the Suneditor README.md for more details on buttons and options.
