PatternFly offers two components for displaying large data sets: the data list and the data table. While they satisfy similar use cases, choosing the correct component to use in your design will be dependent on the type of data you need to display.
Use data lists when:
- A flexible layout is more important than arranging information in a grid
- You want to include active content like a chart
- Content displayed may vary between rows
Use a data table when:
- Users will want to consume data as a grid (i.e. structured rows and columns)
- You want column headers
PatternFly supports several variations of the data list component.
- Toolbar: The toolbar sits above the list and contains controls for manipulating list data. Common actions include filtering, sorting, and pagination.
- Row: Row height may be variable and sizes to the content. Rows in a data list may take any supported layout.
- Inline actions: These actions apply only to the current row/item.
Use a data list when the information you want to display is not easily structured into a tabular format, you want a more flexible layout within rows, or you plan to embed rich content like a chart or an image into a row.
The data list is not recommended for displaying content that is better presented in tabular format with well defined columns and headings. Instead, use a data table.
Alternative to a data list include data tables or card views. Card views and data lists have similar properties, but information in a card view is chunked into a grid of individual cards. In choosing between a data list and a card view, consider the type of data that will be displayed and the format that best suits that data. If you cannot easily fit all of the data that needs to be displayed into a card, a data list might be a better solution.
Think of each row in a data list as a container for some formatted content. In PatternFly 4, data list rows can accept any layout supported by the design system as long as all rows apply the same layout. Here are some common layouts that may be useful in a data list:
- Grid: when you want to display content in a responsive grid
- Level: when you want to justify content evenly over the width of the row
- Split: when you want to distribute content evenly with a main content area in the center
The actionable data list provides checkboxes that enable users to select one or more rows and act on that selection using options in the toolbar.
- Checkbox: enables a user to select a row
- Global actions: actions that can be applied to all selected items
Use actionable data lists when you need to enable a user to select and act on multiple items in the list.
Do not use actionable data lists when actions are restricted to a single row or object. In this case, place actions inline within the row.
The expandable list adds an expansion panel to every row to reveal more details about the item.
- Expansion caret: toggles the expansion open and closed
- Expansion panel: a container that is revealed when the expansion is open. It can accept any supported layout to present additional content to the user.
Use an expandable data list when you have more information than will comfortably fit inside a row, or you want to provide a way for advanced users to access information that is not applicable to all users.
- Standard data table: combines the styling of a list view with behaviors that are commonly associated with a table (sometimes referred to as a hybrid list)
- Compact data table: maximizes the amount of data that can be displayed in a small space
- Toolbar: sits above the list and contains controls for manipulating table data. Common actions include filtering, sorting, and pagination.
- Select all: when present, selects all items in a table. If pagination is being used, this will only select items on the current page.
- Column headers: should align with the content they contain. If the user is able to sort on a column, the first click on the header will sort the content of the table on the content in that column. Subsequent clicks will toggle the direction of the sort. Table data can only be sorted on one column at a time.
- Select checkbox: selects this row
- Global actions: actions that apply to all selected items
- Inline actions: actions that apply only to the current row/item
- Pagination footer: when present, provides navigation to additional pages
Use a standard data table when the information you want to display fits into a structured, tabular format (i.e. has distinct rows and columns).
Do not use for less structured or variably structured data that cannot be easily organized into columns. In these situations, use a data list.
Consider the structure of the data you want to display and organize that information into columns. Columns will typically have column headers. Every row within a table must have a consistent format. If the table row includes actions, they should always be placed in the rightmost column(s).
Use a compact data table when you want to show as much data per page as possible and readability is a secondary concern.
- Expansion: expands the row
- Expansion panel: contains details associated with a row
Use when you have more information than will comfortably fit inside a row or you want to provide a way for advanced users to access information that is not applicable to all users.
- Expandable cell: a cell that can be clicked to reveal more detail about an item. If the expansion for an item is already open, clicking on a different cell will close the current item and open a new one.
- Expansion panel: contains details associated with an expandable item.
Use a compound expandable list when you want multiple expansion panels that relate to specific table columns where it would not make sense to combine all of this information into a single, simple expansion.
The PatternFly 4 data table is designed to be fully responsive. When columns no longer fit within the width of the viewport, columns are stacked so that data in each row is displayed as sets of attribute-value pairs.
Lists or a tables should be placed in the body of a page. The width should be set by the containing element.
In this example, a data table is positioned in the body of a page in a card.
