Parameters​

To configure the columns appearance, in the columnShape object you can specify the following parameters:

  • menu - (optional) an object of parameters of the columns context menu. Here you can specify the following parameters:

    • show - (optional) - enables/disables a column context menu
    • items - (optional) an array of objects containing parameters of items of the columns context menu. For each item you can specify the following parameters:
      • id - (optional) an ID of the menu item. To implement the built-in actions, you need to specify the following values:
        • "add-card" - defines the action to add a new card
        • "set-edit" - defines the action to edit a column name
        • "move-column:left" - defines the action to move a column left
        • "move-column:right" - defines the action to move a column right
        • "delete-column" - defines the action to delete a column
      • icon - (optional) a class name of icon of the menu item. Here you can specify any icon related to the icon fonts (mdi-delete)
      • text - (optional) a name of the menu item
      • disabled - (optional) a state of the menu item (active or disabled depending on the boolean value)
      • onClick - (optional) a custom callback function, that takes the following arguments:
        • id - an ID of the current menu item
        • item - a data object of the current menu item
        • column - a data object of the target column
    info

    You can also set the items parameter to a custom function, that takes the following arguments:

    • column - a data object of a current column

    • columnIndex - an index of a current column

    • columns - an array of objects containing all columns data

    • store - an object of dataStore

    This function allows customizing menu for any column or hide it for a specific one (by returning null or false):

    items: ({ column, columnIndex, columns, store }) => {
        if(column.id === "inprogress")
            return null

        if (column.id === "backlog") 
            return [
                { id: "set-edit", icon: "wxi-edit", text: "Rename" },
                {
                    id: "delete-card",
                    icon: "wxi-delete",
                    text: "Remove card"
                }
            ]
    }

  • fixedHeaders - (optional) freezes column headers during vertical scroll (true by default). Scroll must be enabled in Kanban itself (height must be limited)

  • css - (optional) a function that returns a css class that applies to columns conditionally

  • headerTemplate - (optional) the HTML template of the column header in the expanded state

  • collapsedTemplate - (optional) the HTML template of the column header in the collapsed state

  • confirmDeletion - (optional) shows/hides the confirmation dialog that allows users to confirm or decline the column deletion

Default config​

const getDefaultColumnMenuItems = ({ column, columnIndex, columns, store }) => [
    { id: "add-card", icon: "wxi-plus", text: "Add new card" },
    { id: "set-edit", icon: "wxi-edit", text: "Rename" },
    {
        id: "move-column:left",
        icon: "wxi-arrow-left",
        text: "Move left",
        disabled: columnIndex <= 0
    },
    {
        id: "move-column:right",
        icon: "wxi-arrow-right",
        text: "Move right",
        disabled: columnIndex >= columns.length - 1
    },
    { id: "delete-column", icon: "wxi-delete", text: "Delete" }
];
const columnShape = {
    menu: {
        show: true,
        items: getDefaultColumnMenuItems
    },
    fixedHeaders: true,
    confirmDeletion: true
};
