  We consider the Littlewood-Offord problems in one dimension for the
Curie-Weiss models. To be more precise, we are interested in
\[Q_n^{+}:=\sup_{x\in\mathbb{R}}\sup_{v_1,v_2,\ldots,v_n\geq
1}P(\sum_{i=1}^{n}v_i\varepsilon_i\in(x-1,x+1)),\]
\[Q_n=\sup_{x\in\mathbb{R}}\sup_{|v_1|,|v_2|,\ldots,|v_n|\geq
1}P(\sum_{i=1}^{n}v_i\varepsilon_i\in(x-1,x+1))\] where the random variables
$(\varepsilon_i)_{i=1,2,\ldots,n}$ are spins in Curie-Weiss models. This is a
generalization of classical Littlewood-Offord problems from Rademacher random
variables to possibly dependent random variables. In particular, it includes
the case of general i.i.d. Bernoulli random variables. We calculate the
asymptotics of $Q_n^{+}$ and $Q_n$ as $n\to\infty$ and observe the phenomena of
phase transitions. Besides, we prove that the supremum in the definition of
$Q_n^{+}$ is attained when $v_1=v_2=\cdots=v_n=1$. When $n$ is even, the
supremum in the definition of $Q_n$ is attained when one half of $(v_i)_i$
equals to $1$ and the other half equals to $-1$.
