| Bar Chart and Performance Table [Heading] | Performance Information |
| Performance Narrative [Text Block] | The following bar chart and table show you how the Fund has performed in the past, and can help you understand the risks of investing in the Fund. The bar chart shows how the Fund’s Class 2 share performance has varied for each full calendar year shown. The table below the bar chart compares the Fund’s returns for the periods shown with a broad measure of market performance, as well as another measure of performance for markets in which the Fund may invest. Except for differences in annual returns resulting from differences in expenses (where applicable), the share classes of the Fund would have substantially similar annual returns because all share classes of the Fund invest in the same portfolio of securities. The returns shown do not reflect any fees and expenses imposed under your Contract or Qualified Plan and would be lower if they did. The Fund’s performance prior to May 1, 2025 reflects returns achieved pursuant to different principal investment strategies. If the Fund’s current strategies had been in place for the prior periods, results shown may have been different. The Fund’s past performance is no guarantee of how the Fund will perform in the future. Updated performance information can be obtained by calling toll-free 800.345.6611 or visiting columbiathreadneedleus.com.
