Array (Texts) is a grid of text fields. Rows and columns are both subquestions, and participants type into every cell. Use it when you need short texts for combinations of two things, for example one word per product and moment, or a name per role and team.
In the picture: 1 the rows, 2 the columns. Both are subquestions.
Click the purple + in the top bar. The question type picker opens.
Under Array, click Array (Texts). The question appears at the end of the current question group.
Click Your question here and type your question.
Click each row and type its label. The purple + bar below the last row adds a row.
Click each column heading and type its label. The purple + column at the right adds a column.
Select the question to open its settings on the right.
Every cell is stored on its own, as the combination of its row and its column, for example Q027_SQ001_SQ003 for the first row and the first column of a question with the code Q027. In the export, each cell is a column.
