# [NTG-context] Problems with itemize with several columns

It seems that putting \column before itemize of 'c', forces 'c' together with this content. Repeating this step produces what I want:

\startexercici[exercici:operacions-amb-fraccions-2]{multiplicació i divisió} Opereu:
\startitemize[a, columns, three]
\item \startformula 3 \cdot \frac{5}{3} \stopformula
\item \startformula \frac{3}{4} \cdot \frac{2}{5} \stopformula
\column
\item \startformula \frac{1}{3} \cdot \frac{3}{4} \div \frac{1}{5} \stopformula
\item \startformula 5 \div \frac{7}{10} \cdot 7 \div \frac{2}{5} \stopformula
\column
\item \startformula \frac{1}{2} \cdot \frac{1}{2} \stopformula
\item \startformula \frac{3}{2} \div \frac{2}{3} \div \frac{5}{4} \stopformula
\column
\item \startformula \frac{2}{3} \colon \frac{2}{5} \stopformula
\item \startformula \frac{3}{4} \colon \frac{1}{2} \cdot 6 \stopformula
\item \startformula \frac{2}{3} \colon \frac{3}{4} \cdot \frac{1}{2} \stopformula
\stopitemize
\stopexercici

@fv leung said I have to replace frac for dfrac, but it mess up the following content in my book.

Thanks all,

However, this would take you into the footer area (shown by the blue arrows), so item (c) is split: the item label fits into the space at the bottom of the column and so is printed there; the fraction doesn't fit and so is moved to the next column.
