Go to your variant options - titles, pricing can be edited in the quick view.
To edit more details about your variant simply hit the 'settings' icon in the far right of the variant box and the options will appear in a drop down box per variant.
Remember to hit 'Save' when making any changes at a variant level.
To reorder a variant option simply hover over the three dots on the left hand side of the item in the edit field and drag and drop the item to the required location in the order you require.
Be sure to hit save to publish your changes to your product.
You can set the stock levels (inventory) for any variant and once these are sold out customers will no longer be able to book.
However, if you wish to mark a variant as 'sold out' you can also do this at any time by selecting the 'Mark a sold out' check box in the variant's drop down edit field. This will override a variant's available stock levels and customers will no longer be able to book this variant option.
To put the variant back on sale you can simply uncheck the 'mark as sold out' box at any time.
To delete a variant - hit the trash can icon on the far right hand side of the variant option's box and hit 'save' to confirm.
