You can now keep the first row of your Size Chart table pinned to the top while customers scroll, so column labels stay visible on longer charts.
How it works
The sticky header activates automatically when enabled. When your Size Chart table has more than six rows, the first row (your header row) stays fixed at the top of the table as customers scroll through the remaining rows. Charts with six rows or fewer display normally, since there's no scrolling needed to see all the values.
Head over to Styles & Settings
Select Size Chart -> Table
Scroll down to Table Styles
Enable "Sticky first row when scrolling"
Why this helps
On longer size charts, customers often lose track of which column corresponds to which measurement (chest, waist, length, and so on) as they scroll down. Keeping the header row in view means shoppers can always match a value to its correct label, which reduces sizing confusion and misorders.
