We can enable tooltip for dimensions and measures by adding descriptions in their respective LookMLs. Please consider the examples below:

measure: gross_margin {
  description: This measure provides Gross Margin on each sale.
  type: sum
  sql: ${TABLE}.gross_margin ;;
dimension: product {
  description: This field provides the name of the Product sold.
  type: string
  sql: ${TABLE}.product ;;

Once the description has been added for the fields in LookML, the users would start seeing the tooltip for these fields as they hover over them in the Explore window.
